Specification of Letters Patent.

Patented May 29, 1906.

Application filed June 13, 1905. Serial No. 265.083.

To all whom it may concern:

Be it known that I, RUDOLPH Know, a citizen of the United States,residing at Spearfish, in the county of Lawrence and State of SouthDakota, have invented certain new and useful Improvements inRefrigerators, of which the following is a specification.

This invention relates to refrigerators, and more particularly to thattype which are used by merchants and others having large quantities ofprovisions which must be kept cool.

In refrigerators as commonly constructed much difficulty and annoyanceis experienced in hoisting and packing the ice in the icechamber. Asdesigned by me the ice-chamber is preferably placed in the cellar orbasement immediately below the provision-chamber. This has the doubleadvantage of allowing the ice-supply to be easily placed in position andalso keeping moisture away from the provisions.

The object of this invention is to produce a device of this characterwhich will be very effective in operation, which will consume a minimumamount of ice, and which can be cheaply constructed.

For a full description of the invention and the merits thereof, and alsoto acquire a knowledge of the details of construction of the means foreffecting the result, reference is to be had to the followingdescription and accompanying drawing, which is a vertical sectional viewthrough the refrigerator as constructed by me.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawing by the samereference characters.

The numeral 1 designates the wall which surrounds the ice-chamber andwhich is preferably made of masonry, so as to exclude heat to as greatan extent as possible. Wallplates 2 are placed thereonand a floor 3built in the usual manner. ber 4 is built upon these wall-plates and thesides thereof comprise two spaced partitions 5, having an air-space 6between them. Since air is a non-conducting medium, the ex- Theprovision-chamternal heat is thus kept out of the provisionchamber. Anair-inlet 7 is located in the ice chamber, and the air, after enteringthrough this inlet, passes upward around the ice and throughperforations 8 in the floor, and finally emerges through a flue 9 in theupper chamber 4. Since the colder and denser air will be at the bottomof the icechamber, is may be desirable to draw the air into theprovision-chamber through pipes 10, which extend from the floor 3 to thebottom of the lower chamber, and are preferably located opposite to theair-inlet 7. A drainagepipe 11 is so located as to carry away the wateras quickly as the ice melts. In order to insure the desired circulationof air, it may be found necessary to employ artificial means, such as afan 12, located in the flue 9.

It will thus be understood that I have invented a refrigerator in whichthe provisionchamber will be entirely free from moisture and in whichthe ice can be very conveniently placed in position.

Having thus described the invention, what is claimed as new is- Anice-house comprising nonheat-conducting sides and a roof, a perforatedfloor dividing the ice-house into a lower compartment which is used asan ice-chamber and an upper compartment which is used as aprovision-chamber, the ice-chamber being located beneath the surface ofthe ground, an air-inlet pipe leading into one side of the icechamber ata point near the bottom thereof, a series of pipes extending from thefloor to the lower portion of the ice-chamber and located diametricallyopposite to the air-inlet pipe, an air-outlet pipe leading from theupper portion of the provision-chamber, and a fan located in said pipeand adapted to produce a circulation of air from the ice-chamber to theprovision-chamber.

In testimony whereof I affix my signature in presence of two witnesses.
